Genes affected

ANO5 (HGNC:27337): (anoctamin 5) This gene encodes a member of the anoctamin family of transmembrane proteins. The encoded protein is likely a calcium activated chloride channel. Mutations in this gene have been associated with gnathodiaphyseal dysplasia. Alternatively spliced transcript variants have been described. [provided by RefSeq, Nov 2009]

ACMG classification

Classification made for transcript

Verdict is Likely_pathogenic. Variant got 9 ACMG points.

PVS1

Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.

PP5

Variant 11-22270337-C-T is Pathogenic according to our data. Variant chr11-22270337-C-T is described in ClinVar as [Pathogenic]. Clinvar id is 1075891.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr11-22270337-C-T is described in Lovd as [Likely_pathogenic].

BS2

High AC in GnomAdExome4 at 12 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

For these reasons, this variant has been classified as Pathogenic. Loss-of-function variants in ANO5 are known to be pathogenic (PMID: 21186264, 23606453, 25891276, 30919934). This variant has not been reported in the literature in individuals with ANO5-related conditions. This variant is present in population databases (rs146341538, ExAC 0.003%). This sequence change creates a premature translational stop signal (p.Arg642*) in the ANO5 gene. It is expected to result in an absent or disrupted protein product. -
